Filed Aug. 8, 1932 Patented Mar. 28, 1933 JOSEPH P. CONDQN, OF OMAHA, NEBRASKA COMBINED WINDOW GUARD AND SCREEN Application filed au ust 8, 1932. Serial No. 627,849.

-This invention relates to acombined window guard and screen for use on windows of residences and public buildings, and has for its object, broadly, to provide an appliance,

for a window which will prevent ingress or egress therethrough of unauthorized persons or insects, said appliance to be of such construction that it will not obstruct ventilation or daylight and may be conveniently manufactured at a limited expense.

It is an object of the invention to provide a foraminous barrieror obstruction in the form of a combined grid and screen which may be inserted and locked in a window frame, may be readily removed by the owner whenever desired, and will require no changes and will cause no injury to the window frame or woodwork of a building for installation.

The invention includes such a construction that it will not interfere with or prevent the use of storm window sashor other attachments for a window frame, but controls the sliding movement of the upper sash and per- 2 mits a free sliding movement of the lower sash so that, while permitting ventilation, the device will protect against entrance of burglars to residences, store buildings, and

will prevent egress from hospitals or sani-- tarlums.

With the foregoing objects in view the invention presents a new and useful construction, combination and arrangement of parts as described herein and claimed, and as illustrated in the accompanying drawing, it be ing understood that changes may be made in form, size, proportion of parts and minor details, said changes being within the scope of the invention as claimed.

In the drawing, Fig. 1 is a side view'of a combined window-guard and screen embodying the invention, parts being broken away.

Fig. 2 is an enlarged sectional detail showing the lower part of a window frame and window sash together with the grid, the section being on line '22 of Fig. 8.

' Fig. 3 is the view of the inner side of a window frame provided with the grid. Fig. 4 is an end view of the grid frame showing a 50 stationary locking-bar. Fig. 5 is an end view of the grid frame showing a pivotally mounted locking-bar. Fig. 6 is an enlarged detail view of parts in transverse section on line 66 of Fig. 3.

Referring now to the drawing for a more particular description, the invention is shown and described-in connection with certain parts of a window frame 7, such as the vertical parting-strips 8 providing a pair of outer vertical channels 9 for receiving an upper window sash 10, and providing a pair of inner vertical channels 11 for receiving a" lower sash 12.

In order that the objects of the invention may be attained as first mentioned I provide a grid 13 provided with a frame 14, said frame preferably being of rectangular form and constructed of channel iron to facilitate manufacture. However, I do not wish to be understood as limiting myself to the form or kind of material used in construction of any of the parts of the grid.

Numeral 15 indicates a stationary lockingbar which is secured to one end of the gridframe upon the front thereof, said bar hav--, ing an adequate width so that it will project outwardly beyond the end of said frame.

Numeral 16 indicates a second locking-bar which is mounted on the front side of the grid-frame on the end thereof opposite to the bar 15,'the mounting of'this bar being such that it may have swinging movements, a pivot 17 being shown for said mounting.

The locking-bar 15 is provided with projections 18 and 18 at its ends to operate as buffer-members, and as thus described it will be noted that the grid may be readily placed in its normal position in the window frame as shown in the drawing with its locking bar 15 engaging in the outer channel 9 below the upper window sash 10, said locking-bar preventing an outward movement of saidgrid; also it will be noted that the projection or bufier element18 at the lower end of the locking-bar 15 will engage a parting-strip 8 to prevent an inward movement of the grid. The projection 18 at the upper end of the locking-bar 15 operates as a stop. It permits the upper window sash to be moved downwardly a short distance for any desired purpose, as for ventilation, but limits the distance of said downward movement.

The locking-bar 16 has an adequate width so that, when swungdownwardly to a vertical position it may enter a channel 9 to prevent an outward movement of the grid. This locking-bar, at'its lower end, is provided with aprojection or buffer-element 19, and when said bar has been swung downwardly, as mentioned, this projection may engage a parting-strip 8 to prevent a movement of the grid inwardly of the window frame.

In operation, to secure the grid in locked position, the locking-bar .16 is first swung to inoperative position as indicated by broken lines in Fig. 1 of the drawing. The grid is then fitted into the outer part of the window frame.7 as best shown in Fig. 6, the stationary locking-bar 15 engaging in the channel 9 with its projection 18 engaging the parting-strip 8. The locking-bar 16 may then be swung to operative position into a channel 9 with its projection 19 engaging a parting-strip 8.

It will be seenthat an unauthorized person at the outside of a building may be prevented from gaining entrance by operation of the grid. The lower window sash therefore may be completely elevated to permit free ventilation if desired.

preferably of wire mesh which is adapted to be secured to the outer side of the grid by any suitable means.

Numerals 23 (Fig. 6,) indicate recesses formed in the outer side of the window frame 7 for receiving the frame of a storm window sash (not shown). It will be appreciated that all of the parts shown for the devices as described may be constructed of stock material, and since these parts are few and simple, manufacture of the product may be economically conducted.

I claim as my invention,-

In a grid for a window frame provided with channels and parting-strips, a grid having a frame adapted to be fitted into the window frame. a locking-bar rigid with one end of the grid for engaging in a channel and having a projection for engaging a partingstrip, a locking-bar mounted to have a swinging movement on the opposite end of the grid for entering a channel of the window frame and having a projection for engaging a parting-strip, and means on the last named locking-bar for preventing a swinging move;

ment thereof.

In testimony whereof, I afiix my signature.

JOSEPH P. CONDON.

An outward movement of the grid from locking-bars 15 and 16 which normally engage in the channels 9 of the window frame,

and an inward movement of the grid will be prevented by the buffer-elements 18 and 19 which engage the parting-strips 9.

It will be noted that the grid may be conveniently removed from the window frame whenever such removal is required, and that no mutilation or injury of woodwork of a building'is necessary in the use of the device. I Any suitable means may be provided for maintaining the device in locked position. Numeral 20 indicates a small bracket which is secured to the lower part of the grid frame (Figs. 1, 3, 5) for use 1n connection with the projection or buffer-element 19, the latter being provided with an aperture :1: (Fig. 6,) for receiving the locking-latch of a padlock 21 for securing the projection 19 to the bracket 20, said bracket also being provided with an aperture (not shown) for receiving the locking-latch of the padlock.

In instances when the" grid is used upon the window frames of hospitals or Sanitariums where mental diseases are treated it is of advantage to maintain the grids in permanently locked position, and "while padlocks are shown, any other suitable means maybe provided for this purpose.
